0 Assigned ID: 602 ----- Attempting Submission 1 (Fri Mar 06 17:57:17 GMT 2020) ----- HST Phase I Proposal 602 successfully submitted. Receipt: # 602-1 For better compromises with AQUisition imaging versus exposure times, two of the three targets changed compared to the Phase I proposal. The targets are K0, K4, and M0 and the other requirement is that they be in the NGSL, which these targets are. HD 131873 --> BD+41 3306, and HD 061603 --> HD 013520 Other notes: Pointing accuracy on the second orbit is assumed to be +/- 0.01 arcsec (detector changes from CCD to NUV MAMA between orbit one and orbit 2 for all three stars). The "Bright Object Tool" assumes these stars are O stars, which is incorrect. Each case has been checked with the appropriate exposure time calculator and appears to have comfortable "head room" to avoid saturation or damage to the MAMA. -816168860 ----- Attempting Submission 1 (Mon Jun 29 21:41:44 GMT 2020) ----- Calibration of Scattered Light in STIS grating G230LB This calibration proposal measures light scattered by the G230LB grating paired with the CCD detector on STIS. The improvement will have immediate impact on the fidelity of the Next Generation Spectral Library. The observational scheme is to observe three stars of differing temperature in two similar modes; CCD+G230LB and MAMA+G230L. Because the MAMA is mostly insensitive to red light, only the CCD spectra will show the scattered light problem. The scattered light will be modeled and applied to the NGSL. In addition, the dependence of scattered light on the position of the star relative to the centerline of the slit at the time of exposure will be measured. Three bright stars previously observed as part of the NGSL project are chosen at roughly K0, K5, and M1 spectral types. Except for the quantities we intentionally vary, the observing configuration generally mimics the NGSL, in particular, the 0.2 arcsec slit width and the E1 spatial observing position for the CCD spectral observations through G230LB. The observing cadence is two orbits per star, one with MAMA/G230L, the other with CCD/G230LB. Unlike NGSL, we perform the normal peakup to center the star in the slit. After a cr-split exposure, we dither redward and blueward in 0.05 arcsec steps to gauge the impact of off-center object positioning on the properties of the scattered light. The result is 3 stars $\times$ 2 detectors $\times$ 5 or 7 positions within the slit, which should allow a clean calibration of the temperature dependence and slit-position dependendence of the scattered light in G230LB. Dr. Guy Worthey is a stellar populations specialist. He has brought many HST imaging and spectroscopy programs to publication, including GO 6664, AR 8745, GO 9392, AR 13900, and GO 14141, and has supported many more. Several of those deal with local group stellar populations. Team member Xiang Shi is a graduate student researcher who may use this data as part of a dissertation.
